[Elecraft] k1 battery option and mods

[Dave G4AON]

I wholeheartedly endorse the comments by Jim, K4ZM. The back light is 
really nice. I use a pack of 10 x AA sized 2700 mAH NiMh cells in a 
battery holder inside a plastic project box. The battery pack has a 
solid state self resetting fuse and short cable to the K1. It is charged 
with a small home made variable voltage/current bench power supply.
